SPECIFICATION forming part of Letters Patent No. 595,231, dated December*7, 1897. Application filed April 19, 1897. Serial No. 632,859. (Nomodeh) T0 CLZZ whom it may concern.-

Be it known that I, WILLIAM H. W ILDER, a citizen of the United States,residing at Gardner, in the county of lVorcester and State oflilassachusettsdiave invented certain new and useful Improvements inOil-Stoves, of which the followingis a specificatiomreference being hadtherein to the accompanying drawings.

My invention is designed to provide an oilstovc adapted to be used withpetroleum without a wick other than an initial lighting medium; and theobject of my invention is to provide a stove in which the burner andoilreservoir are adjustable in relation to each other, so that theoil-level in the f uel-holder of the burner may be raised or lowered.

In carrying out the invention I employ a reservoir of the type used inthe ordinary student-lamp and thus secure a maintained oil-level, andthis level is controlled by raisin or lowering the reservoir and itsoil-chamber in relation to the burner or by raising or lowering theburner in relation to the reservoir, and it will thus be seen that thelevel of the oil in the burner may be accurately adjusted to therequirements of the work, and after once adjusted this level will beautomatically maintained by the fuel from the reservoir. Thisconstruction renders unnecessary the interposition of the valve in aoneburner stove so far as the ordinary operation of a valve isconcerned-namely, to control the feed of the oil to a burnerbut one maybe interposed with advantage in order to cut off or diminish the flow ofoil without lowering the reservoir or raising the burner to drain thelatter, which otherwise would be necessary, and thus by the use of thevalve the adjusted position of the parts may be maintained and the oiladditionally controlled. IVhere two or more burners are used, it isdesirable to interpose valves, as it may not be necessary to use all theburners in the same way atone time, and in this case the supply to theburners may be regulated by the valves.

In the accompanying drawings I have shown the invention as applied to aform of stove shown in a companion case filed of even date herewith andmarket Case A.

Figure l is a view of a stove with my improvements. Fig. 2 is a detailof the adjusting means for the reservoir. Fig. 3 is a diagram showingthe invention as applied to a stove with a series of burners. Fig. 4. isa detail View of the pipe.

In the drawings, A is the frame of the stove, surmounted by a top B, andsupported within the frame is a liquid-fuel holder having above it acombustioil-chamber both of a construction similar to that particularlyshown and described in a companion case and hence not requiring specificdescription, especially in view of the fact that I do not limit myselfin the present case to the application of the invention to any specificform of burner. The reservoir is shown at O and is seated in anoil-chamber c, the feed being regulated from the reservoir to thechamber by the inlet of the air which enters the reservoir anddischarges more oil as soon as the level of the oil lowers in thechamber. This is a wellknown form of construction. A bracket D extendsfrom the side or end of the stove, and this bracket has four arms (Zextending at right angles, and upon these arms and supported by them isa vertically-movable support E,which may be made slightly bowl shape toreceive the reservoir and its chamber. This support E has triangularpieces e extending from its under faces at equal distances apart, andthese pieces are serrated or grooved 011 their inclined faces and areadapted to rest upon the arms (I. The support E has a handle I by whichit may be turned, and it will be seen that by this operation theinclined faces of the projections e slide over the arms d and thus raiseor lower the reservoir and its chamher and change the level of the oilin the fuelholder of the burner, this level of course be ing always thatof the oil-chamber of the reservoir. The vertical movement of thereservoir and its chamber is permitted by the flexibility of the pipe G,extending between the oil-chamber and the burner, and to securesuflicient flexibility I make the pipe G flattened in cross-section andextend it beneath the burner and make a connection at the side oppositeto that on which the reservoir is located, so as to give sufficientlength to the connection to allow the necessary vertical movement of thereservoir without the connection. A valve II is inserted in this pipe Gto limit or shut off the supply of oil altogether when necessary. Itwill be obstraining Y served, however, that in a single burner the valveis not essential, as the reservoir can be lowered to drain the burnerand thus operate to render further combustion impossible until thereservoir is again elevated.

In Fig. 3 I have shown a diagram in which the burners are indicated atI, and a mainline pipe J is arranged in front of the burners with aconnection therefrom to each burner and with a valve K in eachconnection. The flexible pipe G extends from the oil-chamber of thereservoir to the end ofthe main-line pipe J.

It will be understood that instead of making the oil-chamber adjList-able in relation to the burner the burner may be made adjustable inrelation to the oil-chamber Without departing from the spirit of myinvention.

While I have used the term oil in the description and claims, it will beunderstood that this includes any kind of liquid fuel.

I claim 1. Astove comprising a burner, an oil-reservoir in communicationwith said burner and having a maintained oil-level and means for raisingor lowering one of said parts in relation to the other the other partbeing fixed, substantially as described.

2. A stove comprising a fixed burner, an oil-reservoir in connectionwith said burner and havinga maintained oil-level, andmeans foradjusting the height of the said maintained oil-level in its relation tothe burner, substantially as described.

3. A stove comprising a circular burner, an oil-reservoir in connectiontherewith, and having a maintained oil-level, and means for raising orlowering one of said parts in relation to the other,the opposite partbeing fixed, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

IVILLIAM II. VVILDER.
